The summer, Jacob hit approximately 76 fairways out of the 135 holes he played.
Based on the information provided, Jacob played a total of 135 holes of golf over the summer, and on five out of every nine holes, he hit his drives in the fairway. We can find the total number of fairways hit by Jacob by multiplying the number of holes played by the probability of hitting the fairway.
Calculate the total number of fairways hit:
Total fairways hit = 135 holes * (5/9)
Total fairways hit = 135 * (5/9) / (5/9)
Total fairways hit = 135 * 1 / 1.8
Total fairways hit ≈ 75.88
Since Jacob cannot hit a fraction of a fairway, we can round this number to the nearest whole number:
Total fairways hit ≈ 76
So, over the summer, Jacob hit approximately 76 fairways out of the 135 holes he played.
